Re: [Discuss-gnuradio] QT Vector sink question?

Hi Marcus, Thanks for your note. Yes, certainly I know that I should have not had IQ balance running now, but I falsely assumed leaving the default setting would not hurt anything. Really a major time sink, finding this trivial problem… Concerning your use of the Odroids did you say use VNC

Re: [Discuss-gnuradio] Visualising data with GNURadio

Hi Jaco, this is really a reasonable thing to want, but to be honest, GNU Radio's visualizations are very much oriented along the streaming nature of GNU Radio – and scrollback doesn't fit all to well. I recommend https://github.com/miek/inspectrum , which is relatively new, and relatively cool

Indeed that was the issue. git submodule update fixed. All build and runs now. Many thanks ! Seems that git submodule is a bit confusing for me. -- Tom, N5EG On Fri, Jun 8, 2018 at 9:27 AM, Müller, Marcus (CEL) wrote: > Hi Tom, > > got a bit of worries about this one: > > On Fri,

Re: [Discuss-gnuradio] GNU Radio not installing: Build Failed

Derek, this was much appreciated and seems to have fixed my problems on Centos 7. A note about the C++11 mandatory changes that would help me (and probably others). There are a lot of us who have been forced into using Centos 7 and their so very antiquated tools. Ubuntu's newer tools

[Discuss-gnuradio] Visualising data with GNURadio

Good day, The short story: I have data sets (quite large) in .wav format. I want to perform basic signal processing as well as more complex algorithms on blocks of the data and then display the output. It would be great if one could "scroll" through the data. Are there any blocks that can do

Hi Tom, got a bit of worries about this one: On Fri, 2018-06-08 at 09:17 -0700, Tom McDermott wrote: > modified: volk (new commits) Which basically means that the Volk submodule isn't in the state the main module's branch expects it to be, and that's exactly what's going wrong there.

Re: [Discuss-gnuradio] GNU Radio not installing: Build Failed

Hi Jason, Centos 7 is being specifically looked at for 3.8 as it will define the minimum version of most dependencies. We don't yet have a CentOS 7 regression test VM, but it is something to consider. We will be enforcing the C++11 requirement in CMake which I believe is sufficient to make all

Hi all, my new blog post just went online. I finished all milestones for the first coding period and started to implement the V-BLAST architecture. Next week starts the first evaluation period. Cheers Luca

Re: [Discuss-gnuradio] QT Vector sink question?

Hello Gnuradio Aficionados, In case any has had similar problems with the AIRSPY and spectra aliases, the problem is solved very simply. Do not heave the IQ balance setting at “Automatic” as this causes IQ balancing on Linux devices. This was the cause of our problems with aliases in the

Re: [Discuss-gnuradio] A few questions regarding gr-ieeee802-11

Hi Tal, 3.7 is the maint-3.7 branch, master works towards 3.8, and a milestone of that will be when next is merged into it. You can expect a 3.8 release when next is merged, and all the serious kinks that came with it are contained enough for us to risk a release :) Best regards, Marcus On Fri,

Hi Bastian, Thanks for the clarification about the matched filter -- I basically got the scaling part wrong. Now everything makes sense. About the next into master merge: I understand that currently master is the 3.7 branch and next the 3.8 branch (or is it?), so can we expect a 3.8 release when

Hello Curt, The fix for this issue was merged into the GNU Radio master branch last night. Thank you for posting the PR and describing your solution here. The 3.8 release is going to raise the minimum version requirements of an appreciable number of dependencies in order to make sure that GNU

Hello everyone, I've been playing around with GR and specifically gr-ieee802-11 lately, as I intend to use it soon for a university lab. This tinkering might even result in some code contributions later on (not promising anything though...). At the moment I'm mainly interested in running

[Discuss-gnuradio] Bug in fmdet_cf_imp.cc

Hello, There is a bug in the FM demod. Unbelievably (almost), I reported a bug in the same line a couple of years ago. At that time I also goofed (should have not retyped it). The equation is STILL wrong! Sdot = d_scl * (-S0+d_8*S1-d_8*S2+S4); Should be Sdot = d_scl *

Hello, I've been having a strange problem with the gr-fec block, and I think it may be connected to other issues I'm having. I'm running a flowgraph on the E310 using the LDPC Encoder Definition (via Generator), LDPC Generator Matrix, and FEC Async Encoder blocks and it has been running fine

[Discuss-gnuradio] QT throwing std::bad_alloc

I've had a problem that started about 4 months ago with Qt Gui throwing an exception on startup. I recently installed / rebuilt main-3.7 from git, to see if that bypassed this issue, unfortunately not. The problem occurs with QT GUI Frequency Sink. Disabling it prevents the error. GRC version
